This invention relates to a changeable advertising and display apparatusoperable by a wind vane to move certain parts of an advertising panelsuccessivelyinto a predetermined display position on a bill-board or thelike adapted for use on public highways. a 1 1 The main object' of-theinvention is'to provide a device of the ,character 7 described eachofwhich is designed to hav which is operable by the rotation of a windvane to move an advertlslng panel succes-.

sively from one of several predetermined display positions relative to afixed display opening in thebill-board or the like.

Other. objects of the invention will become apparent as the detaileddescription thereof proceeds. I

In the drawings the invention is shown as a structure comprising a pairof standards 1 and 2, connected by a base 3 and a top rail 4; all framedtogether to support a panel board 5 adapted to receive advertisingmatter and provided at its center I with a display aperture .6. I

The back of the panel board 5,, (Fig. .2), has a pair, of angleirons 7and 8 fixed thereto to formguideways for slida'bly supporting andguiding a panel 9, which, as shown in Fig. 1, is divided into threesections 10,. 11 and 12, each of which is equalin area and outline tothe display aperture 6; Land ing matter displayed thereon.

In order to move the panel 8 so as to cause e advertisthe sections 10,11 and 12 to'appear fully and successively at the display opening 6,

the panel 9 has a pair'of angle iron brack-1 ets l3 and 14: secured toopposite ends of the back thereof andadapted to be engaged by cam hookspivotally secured in certain positions on-the endless sprocket chains;17 and 18. In order to move these chains in opposite directions past theback of panel 9, a pair of vertically disposed shafts 19 and20 arerotatably mounted in hearings 21-2223 and 2l2526, respectively,

suitable secured to the back of the standards 2 and 1, respectively.

The bearings 21 and 24am step bearings in which the lower ends of shafts19 and 20 are supported rotatably; and, the bearings 22-23 and 25-26 arespaced apart to receive grooved, pulleys27 and 28 fixed to shafts 19 and20, respectively. These pulleys 27 and 28 are rotated in oppositedirections by cables 30 and 31, respectively extending around the doublegrooved pulley Y 32 which is fixed to a shaft 33 supported rotatably inbearingsBl and 35 fixedto the back of the top rail 4, the cable 31 beingcrossed to ensure rotation of shaft 20in the opposite direction to thedirection of rotation of shaft 19. A windxvanev' of any suitableconstruction or type is fixed to the upper part of shaft 33 in order torotate said shaft.-

Sprocket wheels 36 and 37, of which the heel 36 is fixed to shaft 19,and wheel 37 is rotatably mounted on shaft between the sleeves 38 and39. The chain 18 is rotated by sprocket wheels 40 and 41 of which thewheel 10 is rotatably mounted on shaft 19, and the Wheel llvis fixed toshaft 20 to rotate therewith. This construction, obviously, ensures thatthe chains 17 and 18-will move in opposite directions pastrthe back ofthe panel 9 regardless of the direction of rotation of shaftBS by thewind vane V.

The "chain 17 moves horizontallypast thej back'of panel 9 and centeredbetweenthe upper and lower ends of the angle 1ron 13.

A hook member 42 is pivoted 'on the upper edge of the chain 17 and asimilar member 43 is pivoted to the lower edge of said chain 17. Thesemembers 4-2 and lizare shaped symmetrically about their pivot axes inorder to adapt tlienifor s'liding in either direction along guidewaysand 45"formed on a cam plate 46 having one end bifurcated and the fur'cations thereof bent around shaft 19 on opposite sides of the wheel 36.

At-one end of the bill-board, the cam plate "46 is supported by'stra'pbrackets 47 and i -8 19 is adapted to contact with either extendingbetween the stretches of the sprocket chains 17 and 18 and suitablysecured to the back of the panel board '5 and is formed with two contactsurfaces 19 and 50 of different lengths. The upper surface edge of thehook member 12 and'keep it in moving :c'ont'act with the angle iron 13for the full lengthof the contact surface 19. The length I et surface459 is substantially equal in length to the Width ofeach of the sections10, 11

' and 12, and surface 50 is twice this length,

in order to effect the movement ofpanel 9 necessary to "locate thesect-ions properly in the displayapert-ureG. I s

j At'the other 'end of the bill-board, a cam plate 51, formedto pairwith the cam plate 46,'is supported by'strap brackets'52 and extendingalso'between the stretches of the s rocket chains 17 and 18 andsuitablysecured to the back of the panel board This plate 51 is formedWitlr'tWO contact surfaces 54 and 55 of difierent lengths, the

' 1e'ngth 0fsurface 55 being equaltothe width of eachfof the sections10, '1' 1 and 12, while the length of surface 55 is equal to twicethisavidth, in order to effect proper successive movements of thedisplay panel-9 relative to the opening 6.

The @uppersurface 54 is adapted to contact With'eitl'ier edge or thehook member 56 pivoted to the upper edge of the chain 18; while thelower contact surface 5511's adapted to contactwlth'the hook niember 57pivot'ed'to thc lower edge'of tl1e cliain18.

These hook members are symmetrically shaped relative to their pivotaxesan order to adapt them for sllCllng":COIltitC'E'lD-Blthfil'direction on i the contact surfaces of the plate 51.

The spacings between the hook members- 42 ant 453 on chain 17, andbetween members I 56 and 57 on chain 18 determine the intervals betweensuccessive movements of the,

display panel 9 at any given speed-0f rotation of the wind vane V. Vdrawings, these spaces are eachequal to onefourth of the entire lengthof each of the chains. Obviously, the distance between the shafts 19 and20 must at least be equal to volves nothing more than the ordinary skillof-the mechanics to design a board having any desired number of displaysections and operated by mechanism'similar in principle of operation tothat disclosedi V ftivill be noted that each of the contact plates 16and 51 has its Wide end bifurcated and bent around the shaft-s 19 and20, re-

;spect *e-lv, "iththe-furcations arranged on opposite .116301 thesprockets 36 and 11,

"respectivelyf While this construction is not actually necessary to theoperation ofthe device, it does afford a-support'ing means to preventlengthwise movements of the, 510a plates 46 and 51onthe back oftheboard. The dlsplaypanel 9'is provided on its bottom edge with'ballcasters 58, 59 andGO,

As shown the equidistantly spaced apart 'to seat'in three of thecorrespondingly spaced" recesses 61,

62, 63, (i l and 65." These recesseshold the panel boardyieldingly fixedin any of its three positions. during the intervals When it is not beingmored by the hook members 4-2 and 43 or and 57. Of course, any de} sirednumber of casters may be used pro- 'vi diJ-g the number of recesses beincreased or 1 tio ng of the display panel 9.

decreased to take care of the proper posi- In operation: Vl hen theshaft33is rotated in either direction by the action of Wind on the vaneV, it is obvious that'the shaft 19 will be rotated by cable 30 in thesame direction; andshaft 20 will berotated in the opposite direction bycable 31..

Referring now to Fig. 4, where the panel 9 shown with the section 11centered in the display aperture 6 and with the hook bracket '13 inorderto move panel 9 With the display section lfi intodisplay positionin the aperture 6. As soon as angle iron13 reached its dotted lineposition indicated member e13 ust engaging the angle iron 3 board.

in Fig. t,the'hook member43 reaches the end of contact surface 50 andswings back to dotted line position. The panel 9 now is positioned asshown in Fig. 5 and chain continues to rotate without moving the panel 9because the channel iron 13 is clear of the cam plate 46. However, theangle iron 14 is located in front of cam plate 51, and the hook member56, riding on cam surface 54, engages channel iron 14 to move the paneltoward the display opening 6; and the hook 57 afterwards moves the panelfrom center position to the extreme left of the The cam hooks on thechains 17 and 18 operate successively on the angle irons 13 and 14 tomove the panel 9 intermittently and through predetermined distances forthe successive display of the sections 10, 11 and 12 of the displaypanel 9 before the display aperture 6.

Since the cam hooks 42, 4:3, 56 and 57 are symmetrically shaped, it isobviously immaterial which direction the shaft 33 is rotated by thewind. The display panel is reciprocated back of the aperture 6 by thesuccessive operation of the two chains 17 and 18 which rotatecontinuously in opposite directions. r

It will be obvious from the disclosure herein that I have provided anovel changeable advertising exhibitor which involves no expense foroperating power, and which can bevery easily and cheaply manufactured.
